Looks good Dennis - some nice detail on Jupiter despite the conditions.

Interesting calculator - I had a look at the "CCD Planetary Critical Sampling" section and put in my own MN190 scope and ASI120 camera details and it says I should be imaging at a minimum focal length of 3689mm for blue light (red and green were less). I use a TV 4 x Powermate to give 4000mm so I guess that's a little over-sampled but not too bad.
